Abstract
The utility model discloses a pure water system pressure balancer with quick couplings, which comprises a pressure pipe and a balance pipe which are arranged in parallel. A cavity body is formed between two opposite lateral surfaces of the pressure pipe and the balance pipe; the middle of the pressure pipe is communicated with the cavity body; a water inlet and a water outlet of the balance pipe are respectively communicated with the cavity body; a sealing film fixing part is arranged in the cavity body; an upper sealing film and a lower sealing film are respectively arranged between the sealing film fixing part and the pressure pipe as well as between the sealing film fixing part and the balance pipe; the middle of the sealing film fixing part is provided with a valve block of which the axial section is of an inverted T shape; the lower end of the valve block is abutted against the water inlet and the water outlet of the balance pipe; both ends of the pressure pipe and the balance pipe are connected with the quick couplings; each quick coupling comprises a pipe end part, a sealing ring, a round installation head and a latch; and the valve block is pushed by the water pressure in the pressure pipe to move down to be abutted against the water inlet and the water outlet of the balance pipe, so that the flow of the balance pipe is reduced and the pressure difference is generated at both ends of the balance pipe.
Description
Technical field
The utility model belongs to water purification machine accessory technical field, is specifically related to a kind of pure water system pressurizer that has snap joint.
Background technology
The RO membrane cartridge of no pump pure water system need connect pressurizer, and to regulate the differential water pressures of RO film both sides, the pressurizer of prior art generally adopts electrically operated valve and controller to regulate, complex structure, and cost is high.The joint of pressurizer generally connects through screw thread in addition, troublesome poeration, and efficient is low.
Summary of the invention
The purpose of the utility model is: the deficiency to prior art exists, provide a kind of simple in structure, and have the pressurizer of conveniently adjusted RO film two side hydraulic pressures of snap joint.
For realizing the purpose of the utility model; Adopt following technical scheme to be achieved: a kind of pure water system pressurizer that has snap joint; Include the force pipe and the balance pipe that laterally arrange; Described force pipe and balance pipe form cavity between relative two sides, are communicated with cavity in the middle of the force pipe, and the entery and delivery port of balance pipe is communicated with cavity respectively; Be provided with the diaphragm seal fixture in the described cavity, be respectively arranged with diaphragm seal, lower seal film between diaphragm seal fixture and force pipe, the balance pipe, and be provided with the valve piece that axial cross section is an inverted T-shape in the middle of the sealing fixture; The entery and delivery port of valve piece lower end and balance pipe offsets; The two ends of described force pipe, balance pipe all are connected with snap joint, and described snap joint includes tube end, sealing ring, circular mounting head and snap close, and sealing ring is installed in the tube end inboard, and the mouth of pipe of tube end is the anticreep mouth that internal diameter dwindles from the inside to the outside; The circular mounting head is installed on the anticreep mouth, and promptly the outer ends of circular mounting head is in the anticreep mouth outside, and it is inboard that inner end extends the anticreep mouth; Circular mounting head the inner is provided with a plurality of arc dops corresponding with the anticreep mouth, and a plurality of arc dops are in the anticreep mouth to deviate from, and the madial wall of arc dop is provided with the metal card article; Snap close is in the anticreep mouth outside and is stuck in the outer end of circular mounting head.
Compared with prior art, the beneficial effect of the utility model is: owing to utilize the water pressure pushing valve piece in the force pipe to move downward the entery and delivery port that props up balance pipe, thus reduced the flow of balance pipe, make the balance pipe two ends produce pressure differential.

The specific embodiment
According to accompanying drawing the specific embodiment of the utility model is done a detailed explanation below.
According to shown in Figure 1; The described a kind of pure water system pressurizer that has snap joint of present embodiment; Include the force pipe 1 and balance pipe 5 that laterally arrange; Described force pipe 1 and balance pipe 5 form cavity 7 between relative two sides, are communicated with cavity 7 in the middle of the force pipe 1, and the entery and delivery port of balance pipe 5 is communicated with cavity 7 respectively; Be provided with diaphragm seal fixture 3 in the described cavity 7, be respectively arranged with diaphragm seal 2, lower seal film 6 between diaphragm seal fixture 3 and force pipe 1, the balance pipe 5, and be provided with the valve piece 4 that axial cross section is an inverted T-shape in the middle of the diaphragm seal fixture 3; The entery and delivery port of valve piece 4 lower ends and balance pipe 5 offsets; The two ends of described force pipe 1, balance pipe 5 all are connected with snap joint; Described snap joint includes tube end 13, sealing ring 12, circular mounting 10 and snap close 11; Sealing ring 12 is installed in tube end 13 inboards, and the mouth of pipe of tube end 13 is anticreep mouths 131 that internal diameter dwindles from the inside to the outside; Circular mounting 10 is installed on the anticreep mouth 131, and promptly the outer ends of circular mounting 10 is in anticreep mouth 131 outsides, and inner end extends anticreep mouth 131 inboards; Circular mounting 10 the inners are provided with a plurality of arc dops corresponding with anticreep mouth 131, and a plurality of arc dops are in the anticreep mouth 131 to deviate from, and the madial wall of arc dop is provided with the metal card article; Snap close 11 is in anticreep mouth 131 outsides and is stuck in the outer end of circular mounting 10.
Described diaphragm seal fixture 3 cooperates upward, and diaphragm seal 2 separates force pipe 1 with lower seal film 6 with balance pipe 5; When the hydraulic pressure in the force pipe 1 raises; Hydraulic pressure moves downward across last diaphragm seal 2 compressing valve pieces 4; Valve piece 4 props up the entery and delivery port of balance pipe 5 through lower seal film 6, and promptly the hydraulic pressure of balance pipe 5 both sides produces difference.
What the tube connector that is connected with snap joint on force pipe 1, the balance pipe 5 was selected for use is the flexible pipe of external diameter sealing ring 12 internal diameters, arc dop coupling.Earlier snap close 11 is taken off, again the tube connector end is inserted, run through circular mounting 10 and sealing ring 12 successively.When the metal card article is passed in the tube connector end, can make above-mentioned arc dop radially outward elasticity open, when running through sealing ring 12 sealing.The rollback tube connector makes the metal card article be clamped on the tube connector lateral wall again, and the anticreep boss on the arc dop tightly is stuck on the anticreep mouth 131, and the rollback stroke is big more, just on anticreep mouth 131, blocks tightly more.Snap close 11 is stuck on the inboard circular mounting of anticreep mouth 131 outsides and annular boss 10 and makes tube connector not deviate from again.
